Answer: a. statistic
Step-by-step explanation:
- Population : It is a set of all possible observations that can be made regarding a study by the researcher.
- Sample : It is finite subset of population that represents the population in the researcher's analysis.
- Population parameter : It is a value that is calculated from the entire population such as population mean , population proportion etc.
- Statistics : It is a value that is calculated from the sample taken out from population.
Since ,The group of people who took poll are representing the sample.
Therefore, 92% of those polled said that a year from now their family financial situation will be as good as it is today or better that means 92% describes a statistics.
Thus , the correct answer is a. statistic
Is it multiple choice? If so, leave the answer choices.
Answer:
34%
Step-by-step explanation:
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
Yess, such fun so
q=number of quarter
n=number of nickles
q+n=63
9.15=915 cents
25 cents=1 q
5 cents=1 n so
915=25q+5n
915=5(5q+n)
divide by 5
183=5q+n
we also have q+n=63
subtract q from both sides
n=63-q
subsitute 63-q for n in second equation
183=5q+63-q
add like terms
183=4q+63
subtract 63 from both sides
120=4q
divdie by 4
30=q
there were 30 quarters
subsitute
63=30+n
subtract 30
33=n
30 quarters
33 nicles
Answer:
26.6 m
Step-by-step explanation:
Given the figures are similar
linear ratio = a : b
area ratio = a² : b²
here
area ratio = 16 : 25, then
linear ratio = 4 : 5 ( square root of both area ratio parts )
let the perimeter of the larger figure be x, then by proportion
= 
( cross- multiply )
4x = 106.5 ( divide both sides by 4 )
x ≈ 26.6
Hence perimeter of larger figure is approximately 26.6 m
